Meiko Ibarazaki is the mother of Emi Ibarazaki. She has been described by Hisao as an older version of Emi, after observing that she acts very much like her daughter. She has a teasing sense of humor, not unlike Emi's, and has made fun of Hisao and Rin by claiming that they seemed to be dating.

She appears a few times throughout the game. In both Emi's and Rin routes, she shows up to watch Emi run at the school track. Later in Emi's route, she is seen at her house, where Hisao was invited over for dinner.
